3.1.3 Washer-nut material Washer nuts shall be made of hot-rolled steel that has been produced by the open-hearth, basic oxygen, or electric furnace process, or of malleable or ductile type ferrous castings. All of these materials shall be of grades and qualities suitable to meet the requirements of this standard. Washers welded to form the washer nuts shall conform to Clause 6 of this standard. 3.2 Dimensions 3.2.1 Bolt length The length of semicone-pointed bolts shall be measured from the underside of the head to the last thread at the end of the bolt. The length of all other bolts shall be measured from the underside of the head to the end of the bolt. The points of double-arming and double-end bolts shall not be included in the length. 3.2.2 Machine bolt heads All machine bolt heads shall be regular square or hexagonal, and shall be in accordance with ANSI/ASME B18.2.1. 4 The dimensions of machine bolt heads before zinc coating shall be as given in Table 1 and Table 2. 3.2.3 Carriage bolt heads All carriage bolt heads shall be in accordance with ANSI/ASME B18.5. The dimensions before zinc coating shall be as given in Table 3. 3.2.4 Washer-head bolt heads All washer-head bolt heads shall have wrench-fit dimensions, be regular square, and shall be in accordance with ANSI/ASME B18.2.1. The dimensions of washer-head bolt heads before zinc coating shall be as given in Figure 1. 3.2.5 Nut dimensions All nuts shall be square or hexagonal in accordance with ANSI/ASME B18.2.2. The dimensions prior to zinc coating are given in Table 4 and Table 5. 3.2.6 Washer nut dimensions Washer nuts shall be square in accordance with ANSI/ASME B18.2.2. The dimensions prior to zinc coating are given in Figure 2.
9.3 Strength and rigidity All staples shall be of sufficient strength and rigidity to resist bending and distortion beyond the point of usability when installed by normal driving methods under normal conditions. 9.4 Protective coatings 9.4.1 Ferrous staples All ferrous staples shall be hot-dip or electro-galvanized. The points of cut or slash point staples need not be galvanized 188.8.131.52 Hot-dip galvanizing Hot-dip galvanizing shall be in accordance with ASTM A153/A153M for class D hardware, the minimum thickness on significant surfaces to be 0.001445 in (0.85 oz/ft 2 ). 184.108.40.206 Electro-galvanizing Electro-galvanizing shall be in accordance with ASTM B633-11 [B8] for type R. S. coating or heavier, the minimum thickness on significant surfaces to be 0.00015 in (0.09 oz/ft 2 ). 9.4.2 Copper-coated staples Copper-coated staples shall consist of a steel wire core with a copper coating thoroughly bonded thereto so that the interlocking crystalline union is secured between the two metals. The copper thickness at any point on the wire before forming into staples shall be not less than 6% of the wire radius. The steel core wire shall be of a grade and quality suitable to meet the requirements of this standard. 9.4.3 Aluminum-clad staples Aluminum-clad staples shall consist of a steel wire core with an aluminum coating permanently and integrally bonded thereto. The aluminum thickness at any point on the wire before forming into staples shall not be less than 10% of the wire radius. The steel core wire shall be of a grade and quality suitable to meet the requirements of this standard. 10. Finish All bolts, nuts, screws, washers, and staples covered in this standard shall be free from burrs, seams, laps, and irregular surfaces that affect serviceability.
defect: Any nonconformance with specified requirements of the tested unit of product. For purposes of this standard, a defect is defined as a unit of product that, when tested, falls below its specified rated ultimate strength. lot: A quantity of line fasteners selected and agreed upon by the manufacturer and customer as being representative of a homogeneous population. Each lot, as far as is practicable, shall consist of units of product of a single type, grade, class, size, and composition that are manufactured at essentially the same time and under essentially the same conditions. Consideration should be given to limit the lot size, where applicable, to each heat-treating and/or annealing process of a group of units. As necessary, the manufacturer shall provide adequate and suitable storage space for each lot and means for proper identification. Any lot shall not exceed 35 000 units. major defect: A unit of product that, when tested, falls below 85% of its specified rated ultimate strength. sample: One or more units of product drawn from a lot, the units of sample being selected at random without regard to their quality. sample size: Based on the lot size. Minimum sample sizes are given in Table 17.
